Entanglement and cooperative effects between the mode components of raman process in cavity and their analogy with atomic collective effects

Abstract

It is proposed the cooperative excitation and absorption of three cavity modes which corresponds to pump, Stokes and anti-Stokes photons stimulated by the atomic inversion. The three modes collective Roman emission is defined introducing the cooperative description between photon of cavity photons. In the case, when the scattering rates in the Stokes and anti-Stokes modes coincide, the SU(2) symmetry is applied for a simple description of this cooperative process. The statistical proprieties and detection method are proposed using the information entropy and atomic correlation functions.
